Filed: 1993-02-04
Granted: 2004-11-02
Abstract: Preparing at a first stage a water absorbed rice of a water content of 38 to 115 parts by weight of water to 100 parts by weight of rice, using hot water, steam and/or steam under pressure, subjecting the resulting water absorbed rice to refrigeration or/and freezing processes, and making the rice further absorb water at a second stage, whereby the total water absorption is 72 to 130 parts by weight to 100 parts by weight of water, a highly water absorbed rice is produced wherein the rice grains are in the state of nearly no gelatinization.      When attempting to prepare an excessively water absorbed rice, a certain degree of gelatinization of the surface conventionally cannot be avoided, so that the taste is deteriorated and the occurrence of gelatinization makes the handling difficult, but in accordance with the present invention, a highly water absorbed rice in the state of nearly no gelatinization can be obtained.      The highly water absorbed rice of the present invention, even after cooked and heated, has hard surface and soft inside, providing delicious taste, so that the rice turns into tasty boiled rice. If freeze dried, the rice turns into excellent instant rice.

Filed: 1992-05-28
Granted: 2003-02-11
Abstract: A fan retractor (100) has a pair of angle-shaped ele-ments (102A, 102B) moveable relative to one another. The angle-shaped elements include first legs (101A, 101B) dis-posed in a generally parallel relationship, and second legs that extend laterally from the first legs, and are adapted for engag-ing with the abdominal wall. The second legs fan out upon ro-tation of the first legs relative to one another and have an ef festive thickness, measured in the direction defined by the first legs, that decreases distally from the first legs. The retractor al-so includes a lifting device (130) that applies a lifting force to the angle-shoped elements. In variations, the second legs have a stiffness that decreases distally from the first legs; the first legs are linked so as to contra-rotate relative to one another; the retractor includes a lifting force indicator (172); and the lifting device unidirectionally applies the lifting force to the angle-shaped elements. The fan retractor is preferably used properitoneally, that is, the second legs of the retractor are in-serted between the properitoneal fat layer and the peritoneum.       With this placement of the retractor, the peritoneum provides a drape over the bowel and omentum and prevents the second legs of the retractor from snagging the bowel or the omentum.       The fan retractor may additionally be used conventionally with its second legs placed posteriorly relative to the perito-neum.

Inventor: WILSON DENNIS R
IPC: E21B23/08
Filed: 1992-09-11
Granted: 2002-11-19
Abstract: This invention relates to a downhole activated centralizer for centralizing pipes in a wellbore (10) for the exploration and production of hydrocarbons. The downhole activated centralizers (50) are carried within either the pipe casing (60) or the collars (90) or both and remain generally within the maximum outward profile of the pipe string so as not to interfere with the movement and placement of the pipe string in the wellbore. The pipe string may be rotated, reciprocated and circulated which enhances the ability of the installer to place the pipe string in a deviated or long reach wellbore. Once the pipe string is in place, the centralizers (50) may be deployed by one of several methods such that pistons mounted in openings in the peripheral wall of the pipe string move outwardly with sufficient force to move the pipe string away from the walls of the wellbore sufficient to form a complete annulus for cementing. Once the well is cemented, the plugs in the tubular pistons may be destroyed by one of several methods opening perforations to the formation.

Title: Technique utilizing stress-induced birefringence for reducing polarization dependent hole-burning in an amplified optical transmission system
Inventor: BERGANO NEAL S
IPC: H04B10/29
Filed: 1994-03-15
Granted: 1998-06-09
Abstract: A technique for reducing signal degradation and fading within a long optical transmission system by minimizing polarization dependent hole-burning ("PDHB") through the cyclic stressing of a birefringent optical fiber to modulate the SOP of an optical signal launched into the transmission system. This effectively reduces the degree of polarization of the launched optical signal, without degrading the noise and dispersion characteristics of the signal. The modulation frequency of the SOP is chosen to ensure that the launched signal does not remain at a particular SOP long enough to anisotropically saturate any optical amplifier employed within the transmission system, and give rise to PDHB.

Title: Method and apparatus for determining clutch touch point
Inventor: OLSON OTIS J
IPC: G01B7/14
Filed: 1995-01-24
Granted: 2000-03-21
Abstract: A vehicle clutch engagement position is disclosed wherein the clutch is moved, under computer control, at a constant rate, from a disengaged position toward a fully engaged position while the transmission is in neutral gear, and the position of the clutch is detected at first and second times (T1 and T2).  Time T1 corresponds to the time when the detected speed of the transmission input shaft is just above the dropout speed of the input shaft speed sensor.  Time T2 corresponds to the time when the detected speed of the input shaft is close to engine speed.  The position of the clutch corresponding to the incipient torque point is extrapolated by subtracting an offset amount from the position detected at time T1.  The offset is equal to the change in position from T1 to T2 multiplied by the square root of the ratio of the input shaft speeds at T1 and T2.

Granted: 1998-06-23
Abstract: Allowing multiple copies of authentication information for a mobile telephone to exist in switching nodes of a distributed switching system. The mobile telephone is only registered on one switching node at a time. One copy is maintained on the resident switching node, and another copy is maintained on theswitching node on which the mobile telephone was last registered other than the resident switching node. If the mobile telephone normal only registers on the resident switching node and one other switching node, the authentication information is present on both switching nodes, and both always have the authentication information to register the mobile telephone stored internally which speeds up the registration process. Further, the authentication information does not have to be repeatly communicated through the distributed switching system. If the switchingnodes are arranged into an authentication hierarchical structure, the authentication information remains stored on a switching node that last used the authenticationinformation within the authentication hierarchical structure, so that all switching nodes in that authentication hierarchical structure can access the authentication information.

Abstract: A drainage system for horizontally sliding closures is disclosed, especially horizontally sliding closures having a solid sill such as is typical with patio doors and the like. The drainage system includes a valve assembly having a top wall, opposed end walls and a side wall that defines a drainage aperture. The drainage aperture is normally closed by a hinged flap which permits water to drain through the valve assembly but inhibits the infiltration of outside air. The valve assembly is mounted over a drainage slot cut through the fixed rail. To ensure most efficient drainage performance, the fixed rail must be vented. This is preferably accomplished by replacing the usual end caps for the fixed rail with slotted end caps which maintain the internal air pressure in the fixed rail with substantially atmospheric pressure. The advantage is a simple, inexpensive very effective drainage system which is suitable for new product and the retrofit of installed doors and/or windows.
